Perhaps you should try some spelling variations:
"designed network optimisation algorithmssss" » "designed network optimization algorithms", "designed network optimization algorithmsssss", "designed network estimation algorithmssss", "designed network estimation algorithmsssss", "designed network optimization algorithmssss", "defined network optimisation algorithmssss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("designed network optimisation algorithmssss") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( designed network optimisation algorithmssss ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimisation algorithmssss") or ("modified objective optimisation algorithm"))*.
